Background: In this study, biogenic synthesis of silver nanoparticles (Ag-NPs) was done by using leaf extracts of Ocimum tenuiflorum and Tinospora cordifolia, Indian medicinal plants. An aqueous solution of silver nitrate was used as a precursor for Ag-NPs. Further, the washing of Ag-NPs was done with the help of centrifuge. Method: These biosynthesized nanoparticles were characterized with the help of UV-Vis spectroscopy, FTIR (Fourier-transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy) with EDX (Energy Dispersive X-ray analysis) and TEM (Transmission Electron Microscopy). Conclusion: It was observed that the reduction of silver ions to silver nanoparticles occurs within 10 minutes of reaction time. Thus, this method can be used for the rapid and ecofriendly synthesis of silver nanoparticles.
